BIOS image for the Lenovo U430 touch version on Quanta board DA0LZ9MB8F0, marked as tested OK in the name and packed as a 3.56 MB RAR containing a .BIN file. Quanta uses DA0 prefixes, and the trailing characters encode the board revision, so compare the full code with the PCB silkscreen. A touchscreen variant may use different firmware from the non-touch U430. Back up the original SPI chip with a programmer and confirm the chip capacity before writing.
